An exploration of React Native Brownfield for web developers, using web concepts like micro-frontends and islands to unpack how native integration actually works under the hood.

A behind-the-scenes look at how we unified iOS, Android, and Web development using React Native Web. We'll cover the challenges that led us to adopt a single codebase, the business and engineering benefits we've seen, how our development workflow supports all three platforms, and the lessons learned from building and scaling a cross-platform product in production.

Even in the age of AI, understanding and using the shell effectively remains an essential skill. This talk explores useful tips, tricks, and lesser-known Bash features that can help you work more efficiently and make your daily terminal experience smoother and more productive.

Guillaume Binet (Founder, Copper Robotics) has 25 years of experience in tech, with 10 years focused on robotics. Previously, he served as CTO at Skyways (Drones), VP of CORE Platforms at Motional (Autonomous Driving), and VP of Onboard Infrastructure at Argo AI (Autonomous Driving). When he's not working on his startup, he likes to scuba dive, race cars, and restore old electronics (family computers and pinball machines).

Effect.ts is TypeScript's "missing standard library": one Effect<Success, Error, Requirements> type covering Rust-style typed errors, concurrency, retries, streams, DI, and schema validation - replacing Zod, Lodash, or RxJS. Composable, type-safe, incrementally adoptable.

Node won server-side JS by being first. Then the guy who built it got on stage and apologised for it. Then a 22-year-old rewrote it in a language most JS devs never heard of and claimed 3x the speed. Then Deno - after years of being ideologically pure - quietly added node_modules support and nobody talked about it.

This talk is the story of how we ended up with three competing JS runtimes, what each one is actually betting on, and why the ending isn't a winner - it's a boring standard that might matter more than all of them.

I run a dev community. Finding events and speakers was chaos.
So I built DevTalkPlanet.com in 200 hours:

Now: 60 events, 100+ monthly users, growing organically.
Free and open-source.

We'll use it live during this talk.
Real commits, real learning, real product solving a real problem.

A walkthrough of a real session where two developers and their AI agent teams collaborated on a complex architectural change — going
from a rough spec to 8 PRs, 4,500 lines of code, and a clean task board in a single day.

The talk covers how we used git worktrees as a shared context surface between two developers' Claude Code agents, spawned specialist
subagents (including a Redis expert that caught two critical production bugs during design review), ran parallel implementation
across multiple branches, and coordinated via a dedicated agent that polled for commits and monitored Slack and CI.

The focus is on the collaboration model — not the technical feature itself — and what the human's role becomes when AI agents can
read, write, test, and coordinate autonomously.

TC39 is working on two proposals, import defer and export defer, whose goal is to allow developers to extract better performance from native ESM, both in the browser and on the server. Let's go together through how they work, and when and where you'll be able to use them!
